gives the cosecant of z.


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • The argument of Csc is assumed to be in radians. (Multiply by Degree to convert from degrees.)
  • .
  • 1/Sin[z] is automatically converted to Csc[z]. TrigFactorList[expr] does decomposition.
  • For certain special arguments, Csc automatically evaluates to exact values.
  • Csc can be evaluated to arbitrary numerical precision.
  • Csc automatically threads over lists.
